Hi All - Can anyone answer how to incorporate performance degradations for an application into Availability calculation.

To be more clear - If an application did not have an outage but just some slowness that caused degradations, how can this be included in the Availability calculation? Or, should this be considered for calculation?

If the service is still available (but slower) why would you want to count it as unavailable? Fudging facts to simplify things has a way of biting back.

Surely the place to define the required response times is in Service Level Agreements?

I suppose if the slowness means that some people cannot access the service then it does also become an availability issue. In this case you can measure the quantity of unavailability, by counting how many people cannot access the service for how long._________________"Method goes far to prevent trouble in business: for it makes the task easy, hinders confusion, saves abundance of time, and instructs those that have business depending, both what to do and what to hope."
